This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
cosmic' to 'verification-done-cosmic'. If the problem still exists,
change the tag 'verification-needed-cosmic' to 'verification-failed-
cosmic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

Title:
[CONFIG] please enable highdpi font FONT_TER16x32
Status in linux package in Ubuntu:
In Progress
Status in linux source package in Trusty:
Won't Fix
Status in linux source package in Xenial:
Fix Committed
Status in linux source package in Bionic:
Fix Committed
Status in linux source package in Cosmic:
Fix Committed
Bug description:
== Justification ==
The console font size on a high resolution screen is only suitable for
eagles, although we can choose a bigger font by running:
sudo dpkg-reconfigure console-setup
But that is not enough, the font size before video driver kicks in is
still small. If we need to debug some early stage issues that will be a
problem.
== Fix ==
ac8b6f14 (Fonts: New Terminus large console font)
Config for this TER16x32 and the compiled-in fonts support needs to be
enabled to keep engineers away from ophthalmologists.
* Disco
It's already there. Just need to enable the configs.
* Cosmic / Bionic
Patch can be cherry-picked.
* Xenial
It needs an extra patch to make it a clean cherry-pick:
* 7bcae826 (lib/fonts/Kconfig: keep non-Sparc fonts listed together
* Trusty
It needs two extra patches to make it a clean cherry-pick:
* fonts: Add 6x10 font (33ac9dba)
* lib/fonts/Kconfig: keep non-Sparc fonts listed together (7bcae826).
And a config entry for the 6x10 font.
Commit "fonts: Add 6x10 font" is just adding a new font.
Commit "lib/fonts/Kconfig: keep non-Sparc fonts listed together" is
just a patch for context rearrangement.
I think these two are safe to be pulled-in.
== Test ==
Test kernels: http://people.canonical.com/~phlin/kernel/lp-1819881-font/
Add "fbcon=font:TER16x32" to the GRUB_CMDLINE_LINUX in
/etc/default/grub, and follow these steps.
* Disco
sudo update-grub; sudo reboot
* Cosmic / Bionic
Add "GRUB_GFXPAYLOAD_LINUX=3840x2160" to /etc/default/grub
sudo update-grub; sudo reboot
* Xenial
sudo update-grub; sudo reboot
* Trusty
sudo update-grub; sudo reboot (I need the proprietary nvidia driver
to boot for my SUT - Dell Precision M3800)
The font before the video driver kicks in will get bigger.
== Regression potential ==
Minimal, changes are limited to adding console fonts, turn on fonts
related kernel configs.
[CONFIG] please enable highdpi font FONT_TER16x32
This is now available in v5.0
config/config.common.ubuntu:# CONFIG_FONT_TER16x32 is not set
